Title:
A Distinguish attack on COSvd Ciphers
Authors: Mohammad Ali Orumiehchi ha, Dr. R. Mirghadri
Abstract:Abstract: The COSvd Ciphers has been proposed by Filiol and others (2004). It is a strengthened version of COS stream cipher family denoted COSvd that has been adopted for at least one commercial standard. We propose a distinguish attack on this version, and prove that, it is distinguishable from a random stream. In the COSvd Cipher used one S-Box (10×8) on the final part of cipher. We focus on S-Box and use weakness this S-Box for distinguish attack. In addition, found a leak on HNLL that the sub s-boxes don’t select uniformly. We use this property for an Improve distinguish attack.
